MN.12.05.1983. Propagation Mysteries Explained with John Brannigan

This edition has African Media News from Richard Ginbey. Mediumwave is expanding in Southern Africa. Parakou in Benin is being heard (later went to the transmitter site). We test a new automatic notch filter made by DATONG with a rather extensive demo. Grundig has announced the Yacht Boy 300. The major part of the programme is an interview with propagation specialist John Brannigan based in Scotland. He was active in the amateur satellite sector. One of the few interviews I have ever conducted where there was virtually no editing. This is fascinating story about what we know and still don't know about the way the ionosphere works. Every heard of a equitorial aurora? Africa Number 1 in Gabon had problems with flutter fading which no-one expected. John explores what mother nature is teaching us.
